oh i had problems too, but i had to do some configs in the audio midi of the computer, but also with live ableton wich is so easy to map te controller, you need to place the inputs in the preferences with the padkontrol on, it will detect it in the midi sync tab and you have to put yes to all.. then when you touch any pad, you will the receive signal upper right some little squares witch turn to color, it means that the program receives the midi signal from de controller, then you use a midi channel, and it will start playing after you put a drum rack or an impulse drum even key sounds, but you have to turn on the last button from the channel you will use, it´ll turn in red as a rec bttn, it´s not difficult, try to do it..
